Mozilla Firefox for Android is prone to an insecure directory permissions vulnerability.

An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions; this may aid in launching further attacks.

Note: This issue was previously discussed in BID 58818 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2013-30 through -40 Multiple Vulnerabilities), but has been moved to its own record to better document it.
